The regression model that can be used to model spatial data is Spatial Autoregressive (SAR) model. The level of accuracy of the estimated parameters of the SAR model can be improved, especially to provide better results and can reduce the error rate by resampling method. Resampling is done by adding noise (noise) to the data using Ensemble Learning (EL) with multiplicative noise. The research objective is to estimate the parameters of the SAR model using EL with multiplicative noise. In this research was also applied a spatial regression model of the ensemble non-hybrid multiplicative noise which has a lognormal distribution of cases on poverty data in East Java in 2016. The results showed that the estimated value of the non-hybrid spatial ensemble spatial regression model with multiplicative noise with a lognormal distribution was obtained from the average parameter estimation of 10 Spatial Error Model (SEM) resulting from resampling. The multiplicative noise used is generated from lognormal distributions with an average of one and a standard deviation of 0.433. The Root Mean Squared Error (RMSE) value generated by the non-hybrid spatial ensemble regression model with multiplicative noise with a lognormal distribution is 22.99.

The blended learning was a learning model that combines offline and online learning. There are two types of blended learning models used in this research, namely the flipped classroom model and the station rotation model. In these models, the teacher would use WhatsApp as a media for online learning. The purpose of this research was to determine the effect of blended learning models on mathematical creative thinking skills and math anxiety of public junior high school students in Sukoharjo Regency, Central Java Province. The research method used was quasi-experimental by sampling using stratified cluster random sampling techniques. There were three schools selected as research samples, namely Mojolaban 1 Public Junior High School, Mojolaban 2 Junior High School, and Grogol 3 Public Junior High School. The data collection used a written test and questionnaires methods which were carried out after the treatment was given. The data analysis technique used a one-way multivariate analysis of variance. This research shows that the blended learning models were better than the direct learning model on mathematical creative thinking skills, but judging from the magnitude of math anxiety, the direct learning model was better than the station rotation learning model.

There are three regions of rainfall that has been formed, each rainfall regions has a variety of homogeneous and there is a correlation between rainfall stations. In each region can be determined rainfall prediction model simultaneously. The model is a model of Vector Autoregressive (VAR) which is an extension of the autoregressive model (AR). Based on this research, we can determine the VAR model by lag 1 or VAR (1) for each region. Region 1 (Anjatan and Sumurwatu), region 2 (Salamdarma and Gantar) and region 3 (Kedokan Bunder and Sudimampir), each of which has a Root Mean Square Error Prediction (RMSEP) of 3.93; 5:03; 4:48; 5.3; 2:18 and 3:53. Correlation value of observations with predictions of rainfall respectively, 0.71; 0.62; 0:57; 0:59; 0.89, and 0.91. Keywords: AR, VAR, RMSEP, correlation

Mathematical literacy is an individual's ability to formulate, use, and interpret mathematics in a variety of contexts. Mathematical literacy ability in context dimension is divided into four, namely personal context, educational and work context, social context, and scientific context. This study aims to describe the mathematical literacy ability of high school students in the context of education and work. The method used in this research is descriptive qualitative. The subjects of the study were three grade X students of SMA Negeri 1 Sragen with low, medium, and high initial mathematical ability categories. The research instruments used were tests, interviews, and researchers. The data collection methods used in the study were the test method and the interview method. Validation of the data used is the triangulation method. The results of the tests and interviews were then analyzed using indicators of mathematical literacy ability to obtain data on mathematical literacy skills in solving problems. The results showed that the students' mathematical literacy skills were low, medium, high in the context of education and work were low. In the case of mathematical literacy in the context of education and work, students with low, medium, and high early mathematical abilities have the ability to interpret problems, apply simple procedural problem solving strategies but have not been able to fulfill the ability to represent different and different answers and communicate solutions.

Pemerintah Desa Rejoso merupakan bagian terkecil dari tatanan pemerintah yang berada di kecamatan Jogonalan kabupaten Klaten. Berbagai permasalahan yang terkait dengan data pada sistem informasi desa data di pemerintah Desa Rejoso adalah adanya kebutuhan untuk memanggil atau menemukan data secara cepat, banyaknya permintaan dari masyarakat maupun dari pemerintah di tingkat kecamatan maupun kabupaten yang meminta data ke desa tetapi tidak bisa terpenuhi dalam waktu yang cepat, serta banyaknya dokumen-dokumen desa yang masih dalam bentuk hardfile sangat rentan hilang. Oleh karena itu, solusi dari permasalahan ini adalah perlu adanya inventarisasi data spasial sebagai bentuk sistem informasi desa. Data dan informasi desa dapat disajikan secara visual dalam bentuk peta digital dan dikemas dalam sistem informasi desa berbasis geospasial dengan memanfaatkan sistem informasi geografis dengan menggunakan software QGIS 3.8.3.
